Salt is formed when a acid reacts with base in a neutralization reaction. Different types of salt are formed depending upon the concentration of hydrogen and hydroxide ions. Neutral salt is formed when concentration of hydrogen ion is equal to concentration of hydroxide ions.

Coffee, orange juice , soft drink, vinegar are acidic substances. Antacid, Baking soda, Detergent, Lye, Milk of Magnesia. water, Sugar, Table salt are neutral substances.

A trolley going down an inclined plane has an acceleration of 2cm/s^2 What will be its velocity
Snowcat [4.5K]

Answer:

V_{f} = 6 cm/s

Explanation:

<u><em>Given:</em></u>

Acceleration = a = 2 cm/s²

Time = t = 3s

Initial Velocity = V_{i} = 0 cm/s

<u><em>Required:</em></u>

Velocity = V_{f} = ?

<u><em>Formula:</em></u>

a = \frac{V_{f}-V_{i}}{t}

<u><em>Solution:</em></u>

2 = \frac{V_{f}-0}{3}

=> V_{f} = 2*3

=> V_{f} = 6 cm/s

Difference between G and g​
garri49 [273]

Explanation:

G is the universal constant of gravitation, approximately 6.67×10⁻¹¹ m³/kg/s².

g is the acceleration due to gravity.  It's defined by the universal law of gravity as:

g = MG / r²

where M is the mass of the planet and r is the distance from the planet's center to the object.

Near the surface of the Earth, g is approximately 9.8 m/s².
